IMPROVEMENT lN MACHINES FOR BURRING WOOL.

Specification forming part of Letters Patent No. 124,119, dated February'27, 1872.

Specification describing an Improvement in Burrin g-Machines, inventedby DANIEL CROW- LEY, of Philadelphia, Pennsylvania.

My invention consists of a device combined with the burring machine, asfully described hereafter, for the purpose of intercepting particles ofwool projected outwardwith thebnrs so that such particles may fall backupon the lmrring-cylinder, instead of passing on with the burs as usual.1

In the drawing, Figure 1 is a vertical sec tion of part of thehurling-machine, with my improvement. Fig. 2, a plan view; and Fig. 3 aperspective "iew of the part to which my invention more especiallyrelates.

B is an ordinary barring-cylinder having journals adapted to bearings inthe opposite side frames A and A. D and D are the feed rollers; F, anendless slatted apron passing around the roller D; and around a roller Eand G is the ordinary winged beater arranged above the burring-cylinder.

As the above-mentioned parts are common to burring-machines it will besufficient to remark that the wool is carried by the endless apron F tothe rollers D and D, and by the latter directly to the burring-cylinderB, which carries the wool around to and beneath the beater Gr. Thebeater Gstrikes whatever burs or other foreign particles are containedin the wool, and throws them into the receptacleH; but particles of woolare frequently projected with the burs into the receptacle, to preventwhich is the object of my invention. I place a comb, I, in avertical, ornearly vertical position, above the burring-cylinder, and in front ofthe beater, so that its teeth will intercept the current of burs andfibers of wool projected by the beater towards the. receptacle. Whilethe comparatively-solid burs will pass freely between the teeth of thecomb, the lighter fibers of wool will be intercepted in their coursetoward the receptacle H by the teeth, and will, owing to the verticalposition of the said comb above the burring-cylinder, fall upon thelatter.

This comb may be permanently fixed in its place; but I prefer to provideit with journals .rzr, adapted to bearin gs in the opposite frames A andA, so that the comb can be raised to the position shown by the dottedlines in Fig. 1, so that should a bur of unusual size catch between theteeth of the comb I can raise the latter over the receptacle H, asshown, and push the said bur into the receptacle.

A guard, 3 is secured to the comb or screen, and projects partially overthe beater for the purpose of preventing burs or particles of wool frombeing thrown outward from the machine by the said heater.

I am aware that fin ger-bars somewhat resembling the comb I have beenused in connection with machinery for burrin g and clean ing wool in thepreliminary treatment of the latter, and before it is in a fit state tobe carded; but such fin ger-bars have been arranged beneath theburring-cylinder, and in a horizontal position, necessitating theremoval of the wool by hand, or the employment of a special fan for thepurpose; the fan also bein g objectionable, inasmuch as the currentcaused by the fan is interrupted by that caused by the heater, and willcarry away many particles of fiber; whereasin myinvention the comb isarranged inavertical, or nearly vertical position, above theburring-cylinder, so that the fibers of wool shall drop from the combdirectly onto the cylinder.

I claim as my invention- The barring-cylinder B, beater G, and comb I,all constructed as specified, and arranged relatively to each other andto the feed-rolls D and D and bur-box H, as and for the purpose hereindescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DANIEL CROWLEY.
